The Illusion of Reality was conceived during my tenure as director of the newly established Division of Information Science and Technology at the National Science Foundation in 1979-1981 as a partial response to the need for a textbook for students, both in and out of government, that would pro vide a comprehensive view of information science as a fundamental constitu ent of other more established disciplines with a unity and coherence distinct from computer science, cognitive science, and library science although it is related to all of them. Driven by the advances of information technology, the perception of information science has progressed rapidly: today it seems well understood that information processing biological organisms and informa tion processing electronic machines have something basic in common that may subsume the theory of computation, as well as fundamental parts of physics. This book is primarily intended as a text for an advanced undergraduate or a graduate introduction to information science. The multidisciplinary nature of the subject has naturally led to the inclusion of a considerable amount of background material in various fields. The reader is likely to fmd the treat ment relatively oversimplified in fields with which he is familiar and, perhaps, somewhat heavier sailing in less familiar waters. The theme of common principles among seemingly unrelated applications provides the connective tissue for the diverse topics covered in the text and, I hope, justifies the variable level of presentation. Some of the material appears here for the first time.

Look around you. Notice your surroundings. What you see seems solid and real, a fixed objective reality existing "out there" separate from you. But it's not, Ralph Strauch argues in this provocative exploration of perception, reality, and the mechanisms that link them. What you perceive are images you create, part of a grand illusion that you participate in and support. The external world is a "rich reality" -- offering far wider possibilities than most of us realize. THE REALITY ILLUSION explores the mechanisms you use to to bring the particular world you experience into focus, and explores the benefits of more fully understanding the collective illusion we call reality.

This work challenges the notion that anxiety and depression amount to a mental illness denoting that something is wrong with the individual sufferer. Instead, anxiety and depression are described as perfectly rational responses to difficulties in the sufferer's world, experienced subjectively by that person. An essential contrast is drawn between objective conceptions of normality (what reality ought to be as per commercial and other objectifying sources) and the reality of the individual's subjective experience of the world (abuse, unemployment, and so on). Chapters include tackling the myth of normality; examining shyness; and analysing the way in which assumptions behind the use of language can foster anxiety and depression. The book's primary purpose is to explain the meaning of anxiety as experienced by the sufferer. These insights also lead to a view, by way of secondary purpose, that the role of the therapist is not in 'curing' the individual, but rather to negotiate demystification and to provide insight into the effects of the problems in the sufferer's world, based on the sufferer and the therapist's shared subjective understanding.

Alexander Unzicker is a theoretical physicist and writes about elementary questions of natural philosophy. His critique of contemporary physics Bankrupting Physics (Macmillan) received the 'Science Book of the Year' award (German edition 2010). With The Mathematical Reality, Unzicker presents his most fundamental work to date, which is the result of years of study of natural laws and their historical development.The discovery of fundamental laws of nature has influenced the fate of Homo sapiens more than anything else. Has modern physics already understood these laws? Many puzzles formulated by Albert Einstein or Paul Dirac are still unsolved today, in particular the meaning of fundamental constants. In this book, Unzicker contends that a rational description of nature must do without any constants.A methodological and historical analysis shows, however, that the underlying problem of physics is deep, unexpected and fatal: the concepts of space and time themselves, the basis of science since Newton, could be fundamentally inappropriate for the description of reality, although-or precisely because-they are so easily accessible to human perception.A new understanding of reality can only arise from mathematics. By exploring the three-dimensional unitary sphere, which could replace the concepts of space and time, the author presents a mathematical vision that points the way to a new understanding of reality.
